I don't proclaim to understand all of VMware's acquisitions of the past few years, but this one is really puzzling.
DynamicOps tools are built on a .NET stack (VMware are clearly a Java shop) and while their platform is a worthwhile in its own right, it duplicates a lot of functionality with products VMware already has or has functionality VMware could build without much effort given the swath of automation tools they already have ( DynamicOps tools just interface with published APIs from Microsoft and Citrix).
Probably a defensive acquisition I guess. I can't see integration with existing VMware products working at all.
